The latest issue of Nintendo Power features a cover story and 7-page feature on BioWare’s mysterious role playing game for the Nintendo DS that stars Sega’s Sonic the Hedgehog. Titled Sonic Chronicles: The Dark Brotherhood, the DS RPG is said to be a stylus-controlled affair similar to The Legend of Zelda: Phantom Hourglass.
According to details from the newest issue of Nintendo Power, the game has a hand-drawn watercolor style. Each member in your party—which can total four of the eleven available characters—will have special abilities (we’re betting the farm on Sonic being fast). Battles are turn-based and attacks are said to follow an Elite Beat Agents model.

I doubt we'll cover this one but we may check in on it occasionally just to keep an eye on BioWare.More information.
